2,,Claims. Cl.6156) This invention relates to load-bearing pile constructions, and particularly to the formation of a tapered enlargement thereon.

, One object of this invention is to provide enlargements to the normal bearing pile section only in that portion of the pile which is in firm *load-carrying soil.

A further object of i vide a load-bearing pile with considerable taper g so that it will develop highload capacities in clay or cohering soil, due both to displacement of the material and to the oblique load-carrying components acting to support the sides of the tapered area; i

Other objects and advantages will become ap- 1 parent as the description proceeds,in which:

Figure 1 is an elevational view,showing a convation showing the pile provided with the concrete reenforced tapered portion;

main body portion of the bearing pile and comprises a conventional type metal H or I-shaped member extending down throughthe water and mud into the-strata of firm soil.

On that portion of the main body portion which penetrates the firm soil strata there is provided an enlargement 3. This enlargement may be a concrete reenforced enlargement, as shown in Figures 1 through 5 or, if desired, may be metal or wooden lagging members. Regardless of the type of enlargement, it is tapered and gradually becomes smaller downward from the top; of the enlarged portion. 7 In the showing, it is to be noted that said enlargement comprises a reenforced concrete member which is approximately flush with the outer faces of the flanges of the H or I-shaped member, and that these two sides, as shown in Figures 2 and 5, are parallel, the tapered portion of the reenforced concrete member extending downwardly from the spaces between the web and flanges of the bodymember 2 for a suitable distance. The concrete enlarged portions 3 are 55 held in position by contact between the web 4 and flanges, 5 of the H or I-shapedmember, as well as by means of suitablereenforclng members this invention is to pro- In the drawing, the numeral 2 represents the 6 and. 1 extending vertical to the axis of the pile and also at right angles to the axis of the pile. The reenforcing members I, which are at right angles to the axis of the pile, extend alternately from each side of the web and are substantially U-shaped in plan, and are provided with depending portions 8 which are adapted to be positioned through apertures 9 in the web and pro-,

ject downwardly on opposite sides of the web, as shown in Figure 3.-

comprising a concrete cast around the main body portion of the bearing pile, with suitable reenforcing members, if desired, this enlargement may be made of other material, such as metal plates fastened with suitable spacers and other attachments, pieces of timber or any other desirable material.

While I have shown and described a specific embodiment of the present invention, it will be terconnected with the web of said bearing pile, said reenforcing means extending vertically and at right angles to the axis of said bearing pile, said reenforcing means at right angles to the axis of said bearing pile being substantially U- shaped and extending alternately from each side of said web and through said openings and provided with downwardly directed portions for interlocking saidnwebwith said vertical reenforc ing means. i i 2. In asteel bearing pile having an H-shaped cross-section, a, concrete enlargement on said i bearing pile in substantial alignment with the outer faces of the flanges of said bearing pile,

said enlargement tapering gradually from its top to its bottom surface, the web of said bearing pile provided with spaced openings, U-shaped reenforcing members extending alternately from each side of the web and through said openings at right angles to the axis of said bearing pile and embedded in said concrete enlargement and reenforcing members vertical to the axis of said bearing pile, said vertical reenrorcing members connected to said U-shaped reenforcing members at right angles to the axis of said bearing pile.
